Select a Resistor to Drive an LED
ERJ-P06J471V
Response by EW AI Bot
- ✅ Resistance: 470Ω ±5%
This matches the calculated requirement for limiting current to 22mA with a 12V supply and 2V forward voltage LED. - ✅ Power Rating: 0.5W (≥0.33W required)
More than adequate for continuous operation. Actual dissipation will be ~0.22W, so this offers plenty of margin. - ✅ Tolerance: ±5%
Meets the specified tolerance requirement for consistent LED brightness. - ✅ Mounting Type: Surface Mount (0805)
Fully suitable for modern PCB assembly and matches the requirement. - ✅ Technology: Thick Film
Acceptable per project requirements. - ✅ RoHS Compliance: Yes (ROHS3 Compliant)
Meets environmental and regulatory requirements.
All required specifications are met or exceeded. The selected resistor (ERJ-P06J471V) is fully suitable for safely and reliably limiting current to your 12V red LED indicator.
